automapper

问题 FYI: it's different from this question Automapper and inheritance from Collection or List Here is my inherited list: public class MyPagedList<T> : List<T> { public int CurrentPage { get; set; } public int TotalPages { get; set; } public int PageSize { get; set; } public int TotalCount { get; set; } public MyPagedList() { } public MyPagedList(List<T> items, int count, int pageNumber, int pageSize) { TotalCount = count; PageSize = pageSize; CurrentPage = pageNumber; TotalPages = (int)Math

问题 I'd like to do something like the following and I'm wondering if someone knows how to do it: Mapper.CreateMap<Worksheet, V2WorksheetModel>().If(pWorksheet=> pWorksheet.VisitLevel == 2); Mapper.CreateMap<Worksheet, V3WorksheetModel>().If(pWorksheet=> pWorksheet.VisitLevel == 3); Worksheet entityVisit2 = MyService.GetWorksheetByID(100); //visit level 2 Worksheet entityVisit3 = MyService.GetWorksheetByID(150); //visit level 3 WorksheetModelBase modelBase1 = Mapper.Map(entityVisit2);

问题 What is the proper way to inject AutoMapper to other layers? I read this blog post , but this code cause exception below An exception of type 'AutoMapper.AutoMapperMappingException' occurred in AutoMapper.dll but was not handled in user code when try mapping in service layer. List<StudentViewModel> list2 = _mapper.Map<List<StudentViewModel>>(list); My AutoFac configuration like below: public static class DependencyRegistration { public static void Config() { var builder = new ContainerBuilder

问题 I try to figure out how to flatten a collection of Merchants, each containing a collection of Orders to a flat List of OrderViewModels. Here my DTO: public class Merchant { public string MerchantName { get; set; } public List<Order> Orders { get; set; } } public class Order { public string OrderId { get; set; } } And Here's the view model: public class OrderViewModel { public string MerchantName { get; set; } public string OrderId { get; set; } } My Goal is to flatten a List<Merchant> to a

问题 I'm trying to ignore a property from source type. I have defined mapping like this: var map = AutoMapper.Mapper.CreateMap<Article, IArticle>(); map.ForSourceMember(s => s.DateCreated, opt => opt.Ignore()); map.ForSourceMember(s => s.DateUpdated, opt => opt.Ignore()); When I call Map function, AutoMapper.Mapper.Map(article, articlePoco); destination's properties gets updated anyway. I'm using the latest stable version downloaded from NuGet. Any ideas why this isn't working ? I have found

问题 For some reason, a loop that I use in an AutoMapper map definition is iterating more than it should. The map definition: Mapper.CreateMap<AdminGameEditModel, Game>() .BeforeMap((s, d) => { foreach (var platId in s.PlatformIDs) { Platform newPlat = _gameRepository.GetPlatform(platId); d.Platforms.Add(newPlat); } }) .ForMember(dest => dest.BoxArtPath, opt => opt.Ignore()) .ForMember(dest => dest.IndexImagePath, opt => opt.Ignore()) .ForMember(dest => dest.Cons, opt => opt.MapFrom(src => String

问题 This is somewhat complicated to explain, so please bear with me. I have an ASP.NET MVC 2 project that is slowly killing me in which I'm trying to take form data and translate it into entities to create or update, depending on the context of the situation. The most relevant parts (pseudo-code): Entity Game Scalar properties EntityCollection<Platform> Platforms And the basic workflow is: Form data -> model bound to a DTO -> mapping the DTO to an EF4 entity with AutoMapper. It all works well

问题 With AutoMapper, I am using a ValueResolver that returns a structure like this struct MyStruct { public int propA; public int propB; public int propC; } class MyResolver : ValueResolver<MyViewModel, MyStruct> { protected override MyStruct ResolveCore(MyViewModel source) { ....return MyStruct data } } I returned a structure because the mapping rules are quite complex and I could not write a custom resolver for each properties as they are related to each other. So my idea was to do this in one

问题 I use projection to map the Entity classes to DTOs using Entity Framework Core. However, projection adds ToList into child collection properties and this slows down the query a lot. Company Entity: public class Company { public Company() { Employees = new List<CompanyEmployee>(); } public string Address { get; set; } public virtual ICollection<CompanyEmployee> Employees { get; set; } ... } Company DTO: public class CompanyDTO { public CompanyDTO() { CompanyEmployees = new List<EmployeeDTO>();
